1.2 Your Safety and Margay’s Safety
The fully assembled display weighs about 68 lbs (30.8
kg). When assembling a wall, you will need two people to handle the Margay.
WARNING
The lamp needs very high voltages to start,
around 15,000 volts.
WARNING
The lamp gets very hot. Allow it to cool before
removing it.
WARNING
The lamp produces lots of light and UV radiation (ultra-violet) as well. UV light can damage
your retinas. After the light leaves the lamp
and passes through the DLP optical engine,
there is no significant UV, although the light
will be very bright.
WARNING
There is no electrical interlock on the screen.
Opening the screen does not turn off the high
voltage to the lamps. s
Opening the rear cover does turn off the high voltage
to the lamp. However, the lamp will still be very hot.
.
The plug on the power cord serves as the disconnect
for this product. No user serviceable parts inside. All
parts replacement is done at the module level by a
qualified service technician.
CAUTION
There are no user serviceable parts inside.
Refer all repair and maintenance to a qualified
service technician.
.
Static electricity can damage sensitive electronic
components.
• Always use a grounding strap with handling the
electronics module or the optical engine if there
are exposed components.
• When shipping these parts, do not use styrofoam
“peanuts.” These carry static electricity and can
damage the parts. Use an anti-static bag, or, if
4
that is not available, wrap the electronics module
in aluminum foil.

2.1 What You Will Do
The series of steps here give only a basic outline of the installation process. See the specific sections for
details (page numbers in parentheses).
Installation
1. Unpack the Margays. Leave the screens in their
containers. You won’t need the screens for a
while.
2. If it was purchased, install the VIM (Video Input
Module) in each Margay. (10)
3. If it was purchased, install the Big Picture key in
each Margay. (12)
4. Build the wall of Margays, leaving the screens off.
(14)
5. Connect the Margays to power (26), picture
source (22 & 24) and communication. (28)
6. Install the screens, starting with the bottom row.
(32)
Configuration
1. Align each optical engine to the screen. (38)
2. Adjust Margay to each of the inputs you will use:
analog computer (44), digital (48), video (50).
3. Color balance the wall. (52)
4. Set up Big Picture, if you are using it. (54)
5. Save your work. (62)

2.2 Installing the VIM (Video Input Module)
It is easier to install the VIM board in Margays before they get stacked in a wall.
The Video Input Module option is installed in the
field.
You will install the VIM (Video Input Module) in the
Margay’s electronics module. (The electronics module is the part the receives all the input and output
cables.)
If the electronics module is installed in the Margay, you will remove it partially.
4. Pull the module up and partly out.
a. It may take a bit of maneuvering to get the connectors at the bottom to come up with the
module.
b. Do this carefully so you do not damage the connectors. All connectors are latched in place.
They aren’t particularly delicate, but they won’t
stand very rough treatment.
1. Turn off the AC power to the Margay and remove
the power cord.
2. Open the door on the right side of Margay (as
viewed from the front) exposing the electronics
module.
5. Install the VIM in the electronics module.
3. Loosen the two screws at the top of the electronics
module.
10
6. Put in the four screws. Be sure the VIM is pressed
well into the socket.
One of 4 screws.
7. Put the electronics module back in place and
secure it with the two screws.
8. Reconnect power, if you removed it earlier.
11
2.3 Installing the Big Picture Key
Clarity’s Big Picture™ key allows a wall of Margays to spread one picture over the entire wall.
The Big Picture key is installed in the field. You can
install the Big Picture key without removing the electronics module.
3. Plug the BP key into its socket.
1. Open the door to the electronics module.
CAUTION
Be sure all six pins go in the socket holes. If
the key is installed incorrectly, the entire electronics module may not function at all.
2. Remove the cover of the Big Picture key socket.
4. Replace the BP key cover.
The Big Picture key can be installed while the Margay
has power. However, the key will not take effect (Big
Picture will not work) until power is cycled on again.
12
13
2.4 Building the Wall, First Row
It is most important to make the first row straight. Do not put the screens on yet.
Laying the first row
1. Set the first row of Margays side by side without
the screens. Bolt them loosely together near the
bottom with the long side-to-side bolts, washers
and wingnuts.
2. Attach the screen supports to the front edge of the
first row. The screen support only mounts one
way and is used on the bottom row only. It provides a stop or rest for the bottom screens.
3. Check the straightness of this row. This first row
must be absolutely straight.
Do not use your eye alone to judge straightness. Use a
tightly stretched string or a very long level. It is ok if the
row is not level, as would be the case in a tilted wall, but
it must be straight.
4. Use shims under the Margays to make the row
straight vertically.
5. When the row is straight, tighten the bolts holding them together. Then check straightness one
more time.
6. Go to next section (page 16).
Why is straight so important?
All Clarity display that stack must have a straight
first row. If the first row is not straight, the arrangement gets worse as the wall goes up, and the screens
won’t align properly.
Margay is a little more critical of straightness,
because its screens have almost no mullions.
The mullion is the outside border of the screen. In
most Clarity products this is a narrow edge of metal
that holds the screen in place. In Margay the mullion
is a thin piece of tape.
The advantage of this “mullion-less” screen is that
the finished wall will have almost no black lines
between images on the screens.

15
2.4 Building the Wall, First Row
2.4.1 Building the Wall, Second Row and Up
If the first row is straight and solid, the rest of the rows will be easier.
Continuing to build the wall
1. Stack another row of Margays on the first row. As
you stack, be careful with the pins that align the
rows.
3. Then bolt the Margays top-to-bottom through the
top-to-bottom hole using the Vertical bolts,
¼"-20.
2. As each Margay is placed in the second row,
secure it to the lower unit with two Front screws.
16
4. Bolt this row side-to-side as you did the first row.
This time the bolts will go through four Margays,
two in the first row, two in the second rows. The
end of the row has shorter side-to-side bolts to
secure just two Margays together.
CAUTION
For high walls, over 2 units high, and for all
tilted walls, see the safety instruction below.
Safety with high or tilted walls
Because the Margay is so narrow front to back,
there is a danger of tipping with high walls. Margay
has tie-back points on the rear to prevent this.
Use these tie-backs to secure the Margay wall to a
structural part of the building. Don’t wait until the
wall is finished. Do this as you build the wall up.
If the wall is tilted forward, tie the Margay all the
way up.
5. Check straightness of this second row.
The tie-back points are ¼”x20 threaded holes.
6. Continue in this way with the rest of the rows,
checking straightness as you go.
Make sure the fronts of the
units are flush with each
other. This will make screen
alignment easier.
17
2.4 Building the Wall, First Row
2.4.2 Building a Banner, Upside Down
It is possible to hang a single row of Margays upside down to make a banner. Be sure the ceiling can
hold them.
Clarity does not provide any special brackets to hang
a Margay upside down. There are too many variables
to consider, so the method to use is best determined
on site.
Whatever you use to attach Margays overhead, it
must be capable of sustaining five (5) times the
weight of a Margay, which is 68 lbs or 30.8 kg. The
mounting system must therefore hold 340 lbs or 154
kg for each Margay.
You may use the screen supports to cover part of
the Margay, but they are not necessary in the upside
down configuration.
Inverting the picture and menus
In the Miscellaneous menu (under Advanced
Options) check Inverted Installation. This one check
mark inverts the picture and the menus. It also
reverses the left-right of the optical engine alignment
motors so left and right will be correct for you.
MENU > ADVANCED OPTIONS > MISCELLANEOUS
Screens when inverted
The screen supports, which normally hold screens
up, will now be above the row of screens. You may
wish to devise some way to push the screens up from
the bottom to press them against this support to prevent a gap.
It is not necessary, of course, to use the screen support parts in an inverted installation.

2.5 Connections
Margay has four groups of connectors. All inputs are paired with loop-thru outputs (except RS232 In).
The inputs are toward the rear of the Margay.
Analog and digital connectors
Two analog connectors and one digital (DVI) connector have their separate loop-thru outputs. The
Analog outputs (buffered) always carry the corresponding analog input picture.
The digital output is different. The digital output
carries a digitized version of the selected input. If you
change the active input in the Picture menu, the digital output changes.
• See 2.5.1 “Connections, Analog & Digital
Sources” on page 22.
Video connectors
Video connections are optional. The Video Input
Module (VIM) is not installed at the factory; it is
installed in the field by the installer. When installed,
the VIM accepts composite, S-video and component
video (YPbPr). Each input connector is paired with its
separate loop-thru output.
• See 2.5.2 “Connections, Video Sources” on
page 24.
Control connectors
You can control the Margay with a remote control
or with serial commands from a computer or other
device. Send commands in either the RS232 or
RS485 standard.
Normally, you send RS232 commands to one Margay’s RS232 In and loop out the RS485 Out to the
next cube’s RS485 In.
RS485 has better long-distance communication.
• See 2.5.4 “Connections, Control: RS232 &
RS485” on page 28.
Power
AC power (115V or 230V) can be looped thru to
neighboring cubes. The limit on loop-thru is
• 4 Margays when using 115V;
• 8 Margays when using 230V.
The power supply is auto-ranging.

2.5 Connections
2.5.1 Connections, Analog & Digital Sources
The Digital Out connector carries the selected input.
All of the source inputs, the picture inputs, have
loop-thru output connectors. These loop-thrus are
buffered.
• Analog 1 and Analog 2 are 15-pin VGA-type connectors. Margay will accept a wide range of computer resolutions up to 1600 × 1200 and
1920 × 1080. Each of these connectors has a dedicated loop-thru output. These connectors are
also used for RGB video with separate H&V sync,
composite sync, or sync on green; also for YPbPr
video at 480p, 720p, or 1080i.
When an Analog input has a source with sync on green
or composite sync, the DVI Out may not show the
picture properly. If the source is present at power up, it
usually works well, but if you disconnect and reconnect
the source, the DVI loop-thru stops working for these
two types of sync.
• Digital In is a standard DVI cable. It has a loopthru, but this Digital Out connector is not dedi-
PC
cated to the Digital In connector. Instead, the
Digital Out connector carries the picture of the
currently selected input. For instance, if the
Analog 1 connector is selected, the picture on the
Digital Out connector is a DVI version of that
Analog 1 picture.
The DVI does not carry the picture from the composite,
the S-Video, or the component YPbPr inputs.
Limits of loop-thru
No signal can loop-thru forever. There is always
some degradation of the signal along the way.
If you want to loop a single source to a number of
Margays, try one of the methods shown here. In diagram A the signal loops thru six times at most. In
diagram B the signal loops thru four times at most. In
each diagram the cubes marked X is the farthest from
the source.

2.5.2 Connections, Video Sources
Video is a option installed in the field.
If you did not install the optional Video Input Module
(VIM), skip this section. (2.2 “Installing the VIM
(Video Input Module)” on page 10)
Composite video
Connect an NTSC, PAL, or SECAM composite
source to COMPOSITE IN. Loop-thru from COMPOSITE
OUT.
S-video
Connect an NTSC or PAL S-video source to the
4-pin DIN connector, S-VIDEO IN.
Component video
NTSC or PAL rate interlaced video can be fed into
the Y, Pb, and Pr IN connectors and looped out. Be
sure the DVD player is not set to progressive scan.
Use the Analog 1 or 2 connector for progressively
scanned DVD.
When you choose Component Video in the Picture
menu, the Colorspace automatically switches to YPbPr.
When you choose another picture source, Colorspace
switches back to RGB.
Component video YPbPr sources can also be fed
into the Analog 1 or Analog 2 inputs. Colorspace
must be manually changed to YPbPr in this case.
• Use RGB when the analog source is normal RGB.
• Use YPbPr when the source is component analog.
24
The Analog inputs have a greater range of modes for
component than the YPbPr video inputs. If your
YPbPr source does not work in the video inputs, try
Analog 1 or 2.
25
2.5 Connections
2.5.3 Connections, Power
AC loop-thru means you won’t need as many mains sockets.
Bring in AC power next to the electronics module.
The voltage can be 115 (90V – 132V) or 230 (200V –
254V).
Loop the AC power out to the next Margay, if you
wish, but limit this to four (4) connected Margays for
115V operation and eight (8) connected Margays for
230V operation.
WARNING
Do not exceed the recommended number of
Margays linked in series for AC power or the
current draw will be too great.
The AC switch on each Margay controls that cube
only. Turning off the switch in the first cube does not
cut the AC power to the remaining cubes.
The switch is lit when it is ON and there is AC
power to the Margay.
The AC input is fused with a 10A fuse. If for some
reason the fuse in any Margay blows, all the cubes
downstream from this one will go off.

2.5.4 Connections, Control: RS232 & RS485
With serial control, you can control a whole wall, several walls, and any single display in them.
Connect to the computer
Connect the first cube in the wall to the serial out
port of a computer or another type of controller, such
as a video controller. Connect with computer serial
cable, such as Cat-5, using straight-thru cable.
You will probably need to convert the 9-pin serial port
to RJ45 with an adapter, which you can buy in most
electronic stores.
Wiring the adapter
To go from 9-pin D-sub serial connector on the back of
the ccomputer to an RJ45 connector, use a standard
RJ45-to-9-pin adapter. Wire it internally as shown. The
wiring shown for this adapter is correct for straight-thru
cables. Straight-thru cables are wired 1-to-1, 2-to-2,
etc.

Start with RS232 and loop all the rest with RS485.
Information about controlling with RS232 is in
4.4 “Controlling Margay with RS232/RS485” on
page 74.
For best results, the RS485 cables should be
twisted pair. The pairs are pins 3 & 6 (signal) and
pins 1 & 2 (ground). CAT5 cable has the correct
twisted pairs.
28
For very long runs of RS485 cable, it may be necessary to terminate in the last Margay in the string. See
4.4 “Controlling Margay with RS232/RS485” on
page 74.
29
2.6 Installing and Removing Screens
The Margay screens in a wall are quite close together, so the order in which you remove them from a
wall is very important.
WARNING
Do not install or remove any screen until you
have read and understand this section. If
screens are installed or removed improperly,
they may be damaged.
About “no-mullion” screens
One of the best features of Margay is its “zero mullion” screens. The screens are as close together as
possible, which means there is very little dead space
between them.
The Margay screens “float.” When they are
installed, they will move up, down, right and left a little. This floating allows them to be position as close
to each other as possible. Screens next to each other
touch each other.
Floating also means that screens higher in a wall
are resting on the lower screens. The screens in the
bottom row rest on screen supports, the “skirt” at the
bottom that holds all the screens up.
The screens won’t fall off if the screen support is
removed or if screen in the bottom row is removed.
However, they may move down a little.
Avoiding damage to the screens
The close, “zero mullion” screen arrangement
comes at a price: You have to be more careful when
installing and removing screens than with other
Clarity products.
WARNING
Pulling the screens off incorrectly can damage
the screens. See the example on the facing
page.
Avoiding gaps between screens
When you install screens in a wall, it is important
to put them on in the proper order.
30
The next two sections describe in detail how to
install and remove screens properly.
2.6.1 “Installing the Screens” on page 32
2.6.2 “Opening or Removing a Screen” on page 34
View from above a row of Margays
When Margays are installed in a row, the
screens are very close together.
Pulling a screen from the outside of the row
causes it to bind with its neighbor.

2.6 Installing and Removing Screens
2.6.1 Installing the Screens
Start in the middle of the bottom row and work outward and upward.
First
1. Be sure the wall of Margays is straight and the
corners are square. Measure the diagonals of the
whole wall. If the diagonals are equal, the wall is a
perfect rectangle.
2. The screen supports should be installed on the
bottom row of Margays.
Screen supports
Then
3. Start in the middle of the bottom row and install
that screen.
a. Pull the screen rails all the way out on both
sides of the Margay chassis.
c. With one person holding each side of the
screen, hang the screen on the rail so the pin
goes into the slot.
4. Slide the screen closed, lifting it slightly so the
screen won’t scrape on the screen support below.
Next
5. Install the screens to the left and right of the center to complete the bottom row.
a. After you add a screen, press it toward the center.
6. Install the screens above the center screen.
a. Left each screen and you press it in so it doesn’t
scrape on the screen below.
b. Continue until you reach the top.
7. Check the line of this bottom row of screens. If
they are not straight, use shims on the top of the
screen support until the screens are straight.
8. Complete the second row, working outward and
pressing the screens inward after they are pressed
home.
9. Working upward and outward, finish all the rows.
Final adjustment
Check all the screens for alignment with each
other. The lines between screens should form straight
lines where they intersect.
b. The screen rails have a large pin and the
screens have an L-shaped slot.
The four corners
should meet like

In a wall of Margays, install the screens starting with the center of
the bottom row and work out to the ends.
Then install the screens above the middle until you have an
inverted T.
Finally, install the rest of the rows, complete each row before moving up.

2.6 Installing and Removing Screens
2.6.2 Opening or Removing a Screen
You will hear the screen latch click and release.
Pulling up a little keeps this screen from rubbing
the screen below. Release the latch at top and bottom of one side.
Removing a screen from a single Margay standing
alone is not a problem. Simply grasp the sides of the
screen and pull forward sharply. The spring latches
will pop loose.
Removing a screen from a Margay in a wall is more
exacting, because the screens are so close together.
On the opposite page, look at the row of Margays.
To remove a screen on the outside column in a wall,
do not start at the outside edge. This seems the logical place to start, but it will cause the outside screen
to crunch against the next screen to the center.
Notice also that if you want to remove a screen in
the middle of a wall, you should work from the outside of the wall inward.
Place suction
cup at these
points
CAUTION
When you pull the edges out, pull out only ½"
(2 cm). That is enough to release the spring
latches without harming the next screen.
Hints
When pulling with the suction cup, always pull at a
4.
slightly up angle. This keeps the screen from scraping
the screen below.

Then pull this edge.

Place the suction cup puller near the corner of the
screen.
Start at the outside and work in.
Never pull the “open” edge first.

2.6.3 Opening a Screen Temporarily for Work
The Margay screen props open for work from the front.
1. Carefully open the screen of the Margay you want
to work on. See 2.6.2 “Opening or Removing a
Screen” on page 34.
2. Pull the screen all the way out.
3. Use the hook to hold the screen at an angle.
4. Be sure to close the hook along the slider before
closing the screen.

3.1 Adjusting Margay’s Engine: Important Step
The optical engine must be adjusted to aim the picture accurately at the screen.
Although the optical engine was perfectly adjusted
when the Margay left the factory, vibration along the
way may have moved it.
CAUTION
It is important to check this mechanical adjustment of the optical engine before any electronic adjustments are made to the picture.
Aligning the optical engine
1. Open the Engine Alignment menu.
2. In the last item in the menu, choose Grid. This
pattern shows all the pixels in the optical engine.
3. Start by positioning the grid pattern to the center
of the screen.
a. The Left and Right Side controls move the left
and right sides of the grid up and down. These
two controls react with one another a little, so
moving the right side may affect the left side,
too.
b. Separately the Left and Right Side controls
adjust rotation of the grid image. Together they
adjust the vertical position.
c. Use the Horizontal control to move the grid
image left and right. Again, this control interacts somewhat with the up and down controls
of left and right.
4. When the grid image is centered, use the Image
Size control to size the image. Try to lose (hide)
one pixel at the edge of the screen.
a. The other pattern, Alignment Dashes can help
you here. This pattern shows the last six pixels
at each edge.
b. To hide one pixel, adjust the size so that you
see five dashes at each edge.
c. There may be a small amount of curvature
(barrel or pincushion distortion) at the edges.
This is normal. You will have no more than
about one pixel of curvature along any edge.
d. The Image Size control may affect the rotation
or position of the image, so go back and forth
between the controls to find the best adjustment.
Hiding one pixel at all sides is ideal. Try to make it at
least one pixel and no more than three.
38
What if you CAN’T move the image enough?
In some rare situations, you may not be able to use
the Engine Alignment menu to move the image far
enough on the screen. If so, you must manually move
the optical engine carriage.
1. If you have moved the image using the Engine
Alignment menu, move the image back to the
“center”. You can find the center of the range of
alignments by finding each extreme and moving
the image to the middle.
By “centering” the alignment engine you will retain fine
image adjustment settings. In the following steps, you
will do gross adjustments to move the image. You must
still do fine tuning of the image alignment using the
Engine Alignment menu.
2. Remove the rear panel (6 ¼-turn screws).
3. The optical engine carriage is exposed. (Cables
normally attached to the optical engine have been
removed for these pictures.)
4. Loosen the two mounting nuts on the left side of
the carriage.
8. To move the screen image up or down tighten or
loosen the adjustment screws on the both sides of
carriage.
Loosen these two nuts
Move image up or down by adjusting this screw...
5. Loosen the single mounting nut on the right side
of the carriage
... and this screw
Loosen this nut
6. To move the screen image to the right, move the
carriage to its left (as you face the carriage from
the back of the unit).
7. To move the screen image to the left, move the
carriage to its right.
a. To move the screen image down, tighten these
screws (turn the screws clockwise).
b. To move the screen image up, loosen the
screws (turn the screws counter-clockwise).
These adjustments are for large physical movement.
You’ll still need to do fine tuning of the picture position
using the process described in “Aligning the optical
engine” on page 38.
9. After you have moved the image to a more reasonable position, tighten the three mounting nuts
you loosened earlier.
10. Now fine-tune the image position as described in
“Aligning the optical engine” on page 38.
39
40
Alignment Dashes
Use the Alignment Dashes pattern
to show how many pixels are visible
at each edge.
Use the Grid pattern to adjust
rotation and to align all patterns in a wall.

3.2 Adjusting Each Margay To Its Source
3.2 Adjusting Each Margay To Its Source
The source picture—from computer, video, DVD—is not always perfect in its size or strength; it does
not always conform exactly to a standard. Margay has a way to compensate for this.
Computer sources vary quite a bit from computer to
computer. They even vary between video outputs on
the same video card. Video sources vary more.
To make the Margay respond correctly to these
non-standard sources we adjust Input Levels.
• Input Levels for computer sources, analog, see
page 44
• Input Levels for computer sources, digital, see
page 48
• Input Levels for video sources, page 50
How does Input Level relate to Color Balance
To make all the displays show the same color and
brightness across the whole wall, you need to adjust
input levels and do color balancing.
You can do Input Levels first, or you can do Color
Balance first. It doesn’t matter. But they must both be
done.
Input Levels and Color Balance do not affect each
other, but they both affect the final picture.
• Color Balancing the displays, page 52
What does Input Level do?
For analog computer sources adjusting to the computer’s picture output means finding what that computer means by black and white.
Black is supposed to be a voltage of zero coming
from the computer’s video card, but it almost never
is. White is supposed to be a voltage of 0.7 volts, but
it usually isn’t either.
The Input Level adjustment process asks you to
provide a picture from the computer that is black,
then one that is pure white. With these, you can
quickly and automatically make the display “learn”
what this computer means by black and white.
The result? Good pictures, using all the dynamic
range of color coming from the computer.
For Input Levels, you must use black and white coming
from the computer you will use for the program. You
don’t make this adjustment with your work laptop and
then switch to another computer for the display’s
program of pictures.
What does Color Balance do?
Color balancing adjusts all the displays in a wall so
they produce the same colors across the entire wall.
42
Displays differ from one another because of very
small differences in the color of the light produced by
the lamp and by differences in the dyes used to make
the color in a DLP™ optical engine.
In color balancing you use the display’s internal
test patterns of white, first, then gray. The internal
pattern assures that a pure white is used.
Selecting the source
1. Press MENU on the remote.
2. Select PICTURE and press ENTER.
3. Select SOURCE and press the lEFT ARROW key.
4. Choose the source you want and press ENTER.
5. Press MENU again to close all menus.
43
3.2 Adjusting Each Margay To Its Source
3.2.1 Adjusting to Computers, Analog RGB
3.2.1 Adjusting to Computers, Analog RGB
The best way to adjust levels is the semi-automatic method.
Adjusting levels semi-automatically
This is quick and easy if you can get a black picture and a white picture from the source computer.
1. Display a black picture from the source. This
must come from the computer source that will be
used for the program. It does no good to use your
laptop for this adjustment, then connect to a different computer for the program. Nor can you use
the Margay’s black test pattern. (Hint: Make a
black screen from Windows Paint program.)
2. In the MANUAL LEVELS menu, select Auto Black
Level and press ENTER. (There are several paths to
the Manual Levels menu as shown in the pictures.)
3. Display a white picture from the source.
4. Select AUTO WHITE LEVEL and press ENTER.
That’s all there is to it.
The Margay is now adjusted to the black and white
levels of this computer using this video card. If you
change computers or video output cards in the computer, you must do this again.
Adjusting levels completely automatically
Open the AUTO SETUP OPTIONS menu and check
DO BLACK/WHITE LEVELS. You can check the other
items, too, particularly FREQUENCY and PHASE.
Now press SETUP. Margay looks for the darkest
pixel and the brightest pixel in the picture and adjusts
itself so that these are the truly the darkest and
brightest.
When the Black/White Levels item is checked, the
Margay will do this automatic level adjustment
whenever a completely new source is displayed.
What is a “completely” new source?
Margay remembers all the values in the last 10 pictures. If a new picture comes from a different source,
such as from a different computer, and that picture
has almost exactly the same resolution, number of
active lines, number of blanking lines, etc., the Margay will assume that this is a source it has seen before
and use the remembered setup values. This is a different sort of memory from the 40 numbered memories described in “Using the Memories Efficiently” on
page 78.
On the other hand, if the new source is sufficiently
different, Margay will engage all the checked processes in the Auto Setup Options menu.
44
When a saved memory is recalled from the Recall
menu, Margay does not do any auto setup.
Which is best: Manual, Semi-Auto, or Auto
The manual and semi-automatic methods are
more accurate. The automatic method is sometimes
not accurate enough for the White Level.
The good news is that you should only have to do
the manual or semi-auto method once for each computer source. Save these settings in the Save menu,
“How to Save to a Memory” on page 80. Then use
Recall to instantly bring it all back.
When to re-adjust levels
You should re-adjust black and white levels whenever:
• the computer is changed;
• the video card in the computer is changed, or you
switch the source for this cube to a different video
card output in the same computer;
you change the electronics module.
Adjusting to computer sources manually
See “Adjusting Input Levels Manually” on page 46.
45
3.2 Adjusting Each Margay To Its Source
3.2.1.1 Adjusting Input Levels Manually
It is rarely necessary to adjust input levels manually. You can skip this section.
Adjusting levels manually
1. Display an all-black picture from the source computer.
2. Press LEVEL on the remote.
3. Select MANUAL BLACK LEVEL and adjust it up and
down with the +/– keys to make the three CENTER
POINT values go to zero. If they do not all touch
zero at the same time, use the individual colors
under MANUAL BLACK LEVEL to adjust them.
Do not go beyond the point where the Minimum just
goes to zero. The idea is to just touch the zero level.
4. Display an all-white picture from the source computer.
5. Select MANUAL WHITE LEVEL and adjust the levels
until the CENTER POINT values just touch 255,
adjusting the individual colors as necessary.
It is not a good idea to use the levels to make all the
displays in a wall match each other. That should be
done with the Color Balance menu. (“Color Balancing a
Wall of Margays” on page 52.)
46
47
3.2 Adjusting Each Margay To Its Source
3.2.2 Adjusting to Computer Sources, Digital
Digital sources do not normally need adjustment, but the controls are there if you need them.
These controls are advance level controls and should
not be adjusted unless you have been briefed by the
factory or are familiar with black level adjustments.
They are used to correct the digital blacks that come
from video cards that have incorrect levels.
Don’t use these controls unless you have been briefed
by Clarity or you are familiar with black level
adjustments. These controls are usually not necessary.
48
This form of the Input Levels menu appears
when the current source is Digital and the
colorspace is RGB.
This form of the Input Levels menu appears
when the current source is Digital and the
colorspace is YPbPr.
49
3.2.3 Adjusting to Video Sources
Video adjustments are quite a bit like the controls on a television receiver.
Adjusting the picture
1. Select a video source in the Picture menu. When
the VIM option is installed (Video Input Module)
Margay has available
a. one composite video,
b. one S-Video, and
c. one component (YPbPr) input.
2. Press LEVEL on the remote.
6. If the color bar pattern has a pluge, you can use it
to adjust Brightness.
These controls are also used for analog sources when
you chose YPbPr Colorspace.
Pluge
Now you have two choices.
• Adjust using any picture from the video source.
• Adjust using a standard color bar pattern from the
source.
Adjusting with any picture
This procedure must be done after you adjust color
balance (page 52).
1. Choose pictures that have blacks and whites represented as well as a variety of colors.
2. Adjust Contrast, Brightness, Saturation and Hue
on one Margay until it looks satisfactory.
3. Adjust all the other Margays in the wall so they
have the same values for Contrast, Brightness,
Saturation and Hue as the first Margay.
Adjusting with color bars
1. If possible, use a color bar pattern from the video
source you will use for the program material. You
cannot use the color bar from the Test Patterns
menu.
2. In the Picture menu, check Blue Only. You should
see only the alternate color bars, all of them blue.
3. Adjust Saturation to make the outer two color
bars match. Match them in brightness; they will
already match in color.
4. Adjust Hue to make the inner two color bars
match.
5. Uncheck Blue Only
When a video source is selected, Auto Setup Options is
not available. Adjustments must be made manually.
50
Adjust Brightness so you cannot
see the different between these

3.3 Color Balancing a Wall of Margays
Color Balancing can be done before or after Input Levels.
The object of color balancing is to make the individual units show the same colors. When we see a red
car move across a video wall from one display to
another, we want it to have the same color for the
whole trip, not change from red to maroon to orange.
The displays naturally have slightly different colors
from one display to the next, because of slight variations in the lamp and DLP™ engine. This cannot be
avoided, but we can compensate for it with color balancing.
Color balancing is subjective. It may seem strange
at first, but it gets easier with practice. Fortunately,
you don't have to match all the colors; you only have
to match whites and grays.
When you make all the displays look the same
with White and Gray, all the other colors will look
the same. It is not necessary to achieve a perfect
white or a perfectly colorless gray. It is only necessary
that all the displays look alike when they display
white and gray.
CAUTION
Never try to match the colors of the display
units with the Black and White Level controls
or with the Video Controls. You will not like the
results if you do.
Color Balancing
1. Turn on all the units in the wall and let them
warm up for at least five minutes. The lamps
must be thoroughly warm before you color balance.
2. For each display, press MISC once on the remote.
3. Set Gamma at the bottom of the menu to either
Video or Film, but be sure this is the same for all
cubes.
4. Set White Boost to Off.
5. Set Test Pattern to White.
Always use the internal Test Patterns for color
balancing, not an external pattern.
52
If the wall has never been color balanced, make sure
you start with the same color temperature setting on
each cube. If you are not interested in achieving a
specific color temperature, use the default of 8500K,
which is the brightest. If the cube has been color
balance before, it will display CUSTOM in its color
temperature setting, because the balance values don’t
match any of the pre-set color temperatures.
6. Look at the Color Balance values on all displays.
All the White balance values should be 100, and
all the Gray balance values should be 7. If any values are not that way, select Reset to Defaults and
press ENTER. This is where you should always
start color balancing.
7. Select Hide Menu and press ENTER on each display. This will remove all the menus so you can
see the whole screen on all displays. (To re-open
the Color Balance menu, press ENTER for that displays.)
8. Look at all the displays together. Stand far enough
away from the wall so you are looking almost
squarely at all of them. Pay attention to the large
central area, not the edges.
9. Find the darkest display. This is the baseline display. Do not change this one.
Color Balance values are saved for all input sources in
the same memory location. Color Balance is the
same for all sources.

10. Pick a display next to the baseline display, above,
below, or to the side. This will be the variable display. Turn on the Color Balance menu for this
variable display by pressing ENTER. Be close to the
display to do this so only this one display has the
Color Balance menu showing.
11. Match the brightness of this variable display to
the baseline display.
• Match brightness first. Move the selector
arrow to White Balance – All.
• With the left key, reduce the brightness until
it matches the baseline display.
• Select the individual colors and adjust the
amounts of Red, Green and Blue to achieve
the best match in color and brightness to the
baseline display.
12. When the first variable unit matches the baseline
unit, it becomes another baseline unit. Turn off
its Color Balance menu with Hide Menu.
13. Choose another variable unit next to any baseline
display, turn on its Color Balance menu, and
match its white to any baseline display.
14. When all displays match in white, change Test
Pattern to Gray so all the displays show an internal gray pattern.
15. The gray values range from 0 to 15, and they are
all now set at 7. Therefore, gray can be adjusted
up and down. Choose a display that has a middle
brightness and that has very little color in gray.
This becomes the first baseline display for gray. It
does not have to be the same as the baseline unit
used for White.
16. Proceed as before, matching the grays one display
at a time. Always work with adjacent displays.
17. When all displays match in gray, turn off the test
pattern on each display.

Copy to Clipboard will save all the current settings to a
temporary memory. You can then make more
adjustments to see if it gets better or worse. Recall from

when AC power is off.
While color balancing, change the White value by a lot,
not just one step. It’s difficult to see one step in White. A
large change will tell you if you are heading in the right
direction.
If you can’t decide which way to go or how to get this
cube closer to the others, try any change. If it is the
wrong change, it will be quickly obvious, and you can
go back. Use the clipboard.

3.4 Spreading One Picture Over a Wall
3.4 Spreading One Picture Over a Wall
Whether you use Clarity’s Big Picture™ or an external video processor, your goal is to make the picture
fit together properly at the edges. When this is done correctly, the viewer does not notice the black
lines separating the screens.
If you have not checked the optical engine alignment
on each Margay, do so now. (See 3.1 “Adjusting Margay’s Engine: Important Step” on page 38.)
Using an external processor
The processor divides a single picture into several
sections and sends each part on a separate cable.
Connect these cables to the proper Margay. You do
not need the Big Picture key is this case.
You can still position the picture with the Margay
controls, or, with most processors, position and zoom
the picture with the processor controls.
Using Clarity’s Big Picture™
Each Margay must have a Big Picture key installed
(“Installing the Big Picture Key” on page 12).
Loop the same source through all the Margays in a
wall (“Connections, Control: RS232 & RS485” on
page 28).
For each cube, set the Wall menu for the same wall
size.
• Wall Width and Wall Height are the number of
cubes wide and high for the picture. This may be
different from the physical wall size. You could
build a 4x4 wall of Margays and use Wall Mode to
put a single picture on the four cubes in the upper
left corner, for instance.
54
• Unit Column and Unit Row is the position of the
Margay in this “wall.”
• Wall Mode, when checked, turns on the Clarity
Big Picture™ feature. When not checked, the cube
shows the whole picture.
Each cube in a “wall” gets the whole picture by looping
the source from one cube to another, or be feeding
them all with a distribution amplifier. The Wall & Aspect
Ratio menu tells the cube what portion of the entire
picture to display.
Scale Mode, Justify and Border Color…
…are explained in the next section, page 56.
55
3.4 Spreading One Picture Over a Wall
3.4.1 Scaling and Cropping
Sometimes the picture does not fit the wall. If the source picture is video from a DVD, the aspect ratio
is probably 1.77 (16x9), the same as HDTV.
The aspect ratio of a picture is its width divided by its
height. 1024 ÷ 768 = 1.33
The aspect ratio of a Margay is 1.77 (16x9), the same
as HDTV. When the source picture’s aspect ratio is
not the same as the Margay wall, you have to do
something to make the picture fit. You have some
basic choices:
• Fill the area both ways. This will produce some
distortion in the picture. Circles will not be
round.
• Put the picture in without distortion and crop off
the sides (or top and bottom).
• Put the picture in without distortion and fill the
extra space with black or some other solid color.
• Force an aspect ratio, such as 16 x 9 or 4 x 3.
This is a 1.77 picture shown on a 3x3 wall of Margays. The picture fills the wall nicely, and there is no
distortion or cropping.
A picture with an aspect ratio of 1.77 is shown on a 3x3
wall of Margays.
56
Let’s start with a 1.33 (4x3) picture, the aspect ratio
of normal TV, and put it on this same wall of Margays. Here is the original picture.
Scale Mode determines how the picture will be made
to fit the wall.
• Fill All means that the picture will touch the borders of the wall all around, even if this means
stretching (and distorting) the picture in one
direction. The picture had to be stretched sideways to fill the screens.
• Letterbox means expand the picture until the first
edges (top-bottom or left-right) touch the border
of the wall, then fill in the other sides with a solid
color.
• Crop means expand the picture until the second
edges touch the border and let the other edges of
the picture fall outside the wall and get cropped.
Here the width is filled, there is no distortion, but
the top is cropped off. This would happen when
the Justify is BOTTOM.
• Widescreen means force the aspect ratio to 16 x 9
(1.77), the standard for many DVD movies.
• Normal forces a 4 x 3 (1.33) aspect ratio, the ratio
of standard television.
No Big Picture key
If there is no Big Picture key, the whole picture will
appear on the screen, and the menu looks like this:
You can’t spread one picture over several Margays,
but you can make the picture fit one Margay is the
ways described above.
Justify determines how the picture will be place in
the wall.
• If the picture is too wide for the wall and is
cropped on the sides, you can choose Left, Center, or Right.
• If the picture is too tall for the wall and is cropped
top and bottom, you can choose Top, Middle, or
Bottom.
• Similar choices are made if the picture is letterboxed.
Border Color determines the color of the “extra”
space around the picture if it doesn’t fill the screen.
The choices are:
• Black
• White
• Red
• Green
• Blue
• Dark Red
• Dark Green
• Dark Blue
When the Scale Mode is Fill All, the Border Color line
will be grayed out, because there will be no border.

3.4 Spreading One Picture Over a Wall
3.4.2 Zoom and Position
Position moves the picture on the screen. This is NOT the same as optical engine alignment. Zoom
adjusts the edges of the picture to make it fit with the other pictures in a wall.
Position
Press the MISC button once to open the Picture
Position menu. The four arrow keys move the picture
on the screen.
The numbers for Horizontal and Vertical Position
refer to the number of pixels from sync to the first
displayed pixel. These numbers get smaller as the
picture moves up and to the left.
Black edge
If you see a black edge on the screen, and you can’t
move the picture to cover the black, you must adjust
the optical engine position. See “Adjusting Margay’s
Engine: Important Step” on page 38 to do this.
Zoom
Zooming is used mainly to make the edges of a
large picture—one that covers many Margay
screens—fit each other side-to-side and top to bottom.
Zoom menu entries
• Image Resolution is the resolution of the source
picture.
• This Cube is the number of pixels this unit is
using of all the incoming pixels, followed by the
size of the wall (from the Wall & Aspect Ratio
menu) and the Column and Row of this unit.
Using Zoom and Position
Picture Position is usually used to center the picture on the screen.
If the screen has a black edge on one or two sides, and
you try to move the picture to cover the black side, and
this does NOT cover it, see “Adjusting Margay’s
Engine: Important Step” on page 38 for help.
Zoom is primarily used to adjust the edges of the picture when one picture is spread over several cubes.
Whether you use Clarity’s Big Picture™ or an external video processor to make one picture cover several
cubes, the Zoom controls can make the edges fit
together.
58
59
3.4.3 Viewport Adjustment
The Viewport menus adjust the image on the DMD™.
What is the DMD?
DMD stands for Digital Micromirror Device. It is
Texas Instrument’s name for their patented chip that
produces the pictures in a DLP™ (Digital Light Processing) system.
The DMD chip is about the size of a postal stamp
and contains, in the case of Margay, 1280 by 720 pixels.
What is Viewport?
The Viewport menu adjust the number of pixels
actually used on the DMD. You can’t increase this
number, naturally, but you can reduce it.
• DMD Resolution shows the resolution of the
DMD chip. This has nothing to do with the resolution of the source picture.
• Viewport shows the number of DMD pixels being
used.

3.5 Saving Your Work & Recalling a Memory
3.5 Saving Your Work & Recalling a Memory
Some saving is done automatically, but there are big advantages to saving your work manually. There
is more information about memories starting on page 78.
How automatic save works
Whatever changes you make with the remote control or RS232 commands, these changes are saved
automatically. If you change sources (switch to
another input connector) and come back to this
source, everything you did before will be “recalled.”
Things will look like they did before.
Suppose you make adjustments to an SVGA
source on Analog 1, then you feed a UXGA source to
Analog 1 and make new adjustments. Then you
switch to the S-Video 1 connector and do some more
setup for it.
Later you switch to the Analog 1 input again, and
this time it has the SVGA source from before. The
Margay will recognize that it has seen this source
before, or at least a source with these characteristics,
and will recall the SVGA settings you established
before.
This kind of recall includes Input Levels, Position,
and Frequency, but it does not include Wall Mode and
any Big Picture adjustments you made. Those need to
be recalled from memory slots.
Manually saving to memory slots
Margay has 40 numbered memory slots, and this
is the best way to save. Recall is fastest from memory
slots.
First, set up the Margay the way you want it,
including all the adjustments listed in this section.
Then press the SAVE button twice. This opens the
Save grid.
Navigate to an unchecked slot number, or to a
checked slot if you want to overwrite what’s already
saved. Press ENTER.
This menu shows all the data that will be saved.
You can’t change anything but the name in this
menu. To save immediately, press ENTER. The appearance of this menu is somewhat different for digital
and video sources, reflecting what is saved for them.
To change the name of the memory slot
The default name is an abbreviated description of
the contents. In this case, the name tells you that the
source is connected to Analog 1, which is an XGA
picture. This cube is part of a 2x2 wall, and it’s the
cube lower left corner (column 1, row 2).
If your customer wants or needs a more descriptive
name, select the Name line and press ENTER.
62
Use the left-right arrow keys to navigate along the
line. Use the up-down keys to change the character at
that point. Press PREV when finished. Then select
Save Now and press ENTER again.
If you have RS232 control, there are commands to
send a string name to a memory slot, saving time.
How to recall a memory slot
1. Press SAVE once to open the Recall grid.
2. Navigate to the slot you want to recall. You can
only land on slot numbers that are not empty
(have checks). Press ENTER to open the Recall
detail menu. If this slot number has exactly the
same settings are currently being used, a (Current) message appears on the top line.
3. The only line you can select is Recall Now. Press
ENTER.
The best practice is to recall settings from memory
slots. It is faster.

3.5.1 Memory: What Is Saved? And Where?
Margay’s automatic memories work well, but the best way to save and recall is with the numbered
memory slots, because they recall everything.
In the Margay some parameters (values) are associated with the mode. The mode is primarily the horizontal and vertical resolution and the vertical
frequency of the incoming source picture. It is more
than this, but if you think of it this way, you will be
close enough.
Some parameters are associated with the input.
The input in this instance means the input connector: Analog 1, Analog 2, Digital, Composite Video,
etc.
Some parameters are global, that is, they are not
associated with either the mode or the input connector. They are universal.

Memory
The Margay remembers that last 10 modes it
received and all the mode parameters associated with
them.
Switching modes
For instance, suppose you set up the Black and
White Levels for a 1024x768 @ 65Hz vertical from a
computer connected to Analog 1. Then later, using
the same input connector but a different computer
you set up the Margay for a 1600x1200 @ 60Hz. You
re-adjust the Black and White Levels, because they
are different.
Still later you plug in the first computer with its
1024x768 @ 65Hz picture. Immediately, the Margay
recognizes that it has seen this signal type before, and
it recalls the Black and White Levels from its internal
memory.
It does not Do Frequency or Phase or anything
else, because it recognizes that this input was used
before, and the previous settings are probably correct.
• The change is immediate. There is no waiting for
the Margay to Do Frequency or Do Phase or any
of that.
• The switch includes the correct input connector.
• The memory slots can be named something specific to your application: “COMPUTER XL-61,”
“MAIN DVD PROGRAM.”
• And there are 40 of them, not just 10.
Possible issue with Mode specific memory
Suppose that after setting up the 1024x768 and
1600x1200 pictures, you connect a third computer
that is 1024x768, but it has a different requirement
for Black and White Level. In this case, the Margay
would use the wrong values for these levels.
To prevent this from happening, use the memory
slots as described below.
Switching input connectors
Now suppose you use Analog 2 to bring in a picture that uses the component YPbPr video. You
change the Colorspace setting to YPbPr. If you switch
back to Analog 1 in the Picture menu, the Margay
switches back to the RGB Colorspace, because Colorspace is specific to the input connector.
Possible issue with Input specific memory
What happens if you switch back to Analog 1 and
the picture there is YPbPr? The Margay has no way to
know this, no way to detect the difference between
RGB and YPbPr, so it will use the wrong Colorspace.
To prevent this from happening, use the memory
slots as described below.
Global parameters
In none of the examples above does the Margay try
to change the Baud Rate or the Color Balance values,
because these items are saved globally.
Memory slots
The Margay has memory slots, 40 of them. Each
slot memorizes all the mode specific and all the input
specific parameters as well as the input connector
used.
When you recall a memory slot, you recall exactly
the way the Margay was set up when the memory
was saved.

4.1 Selecting a Source
The “source” is the picture coming into the Margay. It may be from a computer, a video, or a DVD
player.
Selecting the source
1. Press MENU on the remote.
2. Select PICTURE and press ENTER.
3. Select SOURCE and press the lEFT ARROW key.
4. Choose the source you want and press ENTER.
5. Press MENU again to close all menus.
Selecting a source means choosing an input connector so you can see the picture coming into that input.
If the source you select is not there, you will see a
Source Absent message on the screen. This usually
means there is no picture coming into that connector,
or the picture is not valid.
This message means Analog 2 is selected now, but
there is no picture coming to that connector.
68
69
4.2 Normal Start Up
It is often helpful to know what the sequence of events is when the Margay starts.
Start up sequence
When AC power is turned on, it seems that nothing happens for a few seconds. The electronics module is starting up and initializing itself.
Next, if the optical engine is warm, the fans start.
During this time, you cannot turn the lamp on. It
shortens lamp life to turn it on when it is hot, so the
fans run for a minute or so to be sure it is cool.
(There is a temperature sensor on the optical engine.
If it is cool enough, the cool-down period is skipped.)
After this cooling down period, you can turn on
the lamp. If Auto Lamp On is checked in the Miscellaneous menu, the lamp will strike (begin to turn on)
at the end of the cooling period.
Shut down sequence
When you turn off the lamp, the fan continues to
run for 15 seconds to cool it off.
The lamp fan runs continuously when the lamp is
one, and for 5 minutes after the lamp is turned off.
The intake fan runs:
• during Lamp On,
• for 15 seconds after AC power is applied, during
which time you cannot turn on the lamp,
• and for 15 seconds after Lamp Off.
CAUTION
It is bad practice to turn off the Margay by
turning off the AC power. The lamp does not
cool properly. This may shorten lamp life.
70
71
4.3 Controlling Margay with Remote
You can control Margay with the remote control or with RS232 commands.
Remote control
The remote control projects a series of IR (infrared) pulses to the Margay for control. Aim the remote
control at the screen and press MENU. The main menu
should be visible, if the lamp is on.
• Something is blocking the IR receiver in the Margay.
• IR remote action was disabled by an RS232 command.
The remote control has a large spread of its IR
radiation. It is difficult from a distance to control only
one Margay in a wall. Step closer.
For a complete list of all remote actions, see
7.2 “Remote Control Buttons” on page 116.
Beeper
If Beeper is checked in the Miscellaneous menu,
the Margay will make a beep each time a remote button is pressed (and the Margay receives the signal).
If the Margay cannot perform the requested action,
it will beep three times, a triple beep. Triple beep will
happen whether Beeper is checked on not.
If the remote doesn’t work
• The batteries in the remote are dead or installed
wrong.
• The remote was not aimed at the screen.
72
73
4.4 Controlling Margay with RS232/RS485
Connect the RS232 In to the computer. Loop thru with RS485.
Remote control with serial commands is a good way
to control a wall while it is operating. It’s also an easy
way to control Margays in a wall during initial setup
using one of the Clarity utility programs.
• To address all the cubes with a certain Unit ID,
use an address like *0 or *3.

Cube IDs
When the cubes are connected in a series loop
(2.5.4 “Connections, Control: RS232 & RS485” on
page 28), each cube should have a unique ID. The ID
is set in the Serial Settings menu.
The Group ID and the Unit ID go together to
make the cube’s ID. Each of the two parts has a range
for characters from 0 to 9 and from A to Z (not case
sensitive).
Addressing the cubes
When you send a command, it will have an
address. There are five forms of the address.
• To address all the cubes in this serial loop, use **
for the address.
• To address a single cube, use the specific ID of
that cube, such as A6 or 00 or 1B.
• To address all the cubes with a certain Group ID,
use an address like 3* with will address all the
cubes with the Group ID of 3, but with any Unit
ID. If you have three walls, and all the cubes in
one of the walls have Group ID 3, this type of
command would address only this wall.
74
Baud rate
Each cube’s baud rate must be set to the computer
or controller’s baud rate. The baud rate is not automatically established, as it is in modems.
Terminating the series
If the serial string is very long, you may have to
terminate the last cube in the string for good communication. Check the Terminate RS485 box.
In most instances, this is not necessary. Terminating the string unnecessarily can cause its own communication problems. The guide line is: If it works
without terminating, leave it alone.
ASCII settings
… are explained in the RS232 manual for Margay,
available or the website. Document 077-0007. All the
serial commands are in this document, too. This and
other documents are available from Clarity’s website.
75
4.5 Asset Tag and Display Status
The Asset Tag feature allows you to identify each Margay by its serial number or in other ways.
To see the current Asset Tag, press MONITOR.
• Interlock—If the interlock is Open, the lamp will
not light (unless the interlocks have been
bypassed to service the display).
• Mode ID—the number of the mode (type of signal) currently set
• HPer—the horizontal period in nanoseconds (ns)
of this signal (picture)
• VLines—the number of vertical lines in the picture
This number will be larger than the vertical resolution,
because it includes vertical blanking lines that are not visible.
• Last Fault—the last event that caused that forced
the lamp off, followed by the number of hours and
minutes since that happened, measured in System Hours, not clock time
The Asset Tag is initially blank. You can write in
any short text message using RS232 commands. See
the Margay RS232 Guide, available from Clarity’s
website.

77
5.1 Troubleshooting Tips
Margay has several troubleshooting aids.
On Screen codes
The On Screen code is a series of red and amber
lights that can flash on the screen to tell you what is
wrong. These flashing lights are particularly helpful
when the lamp won’t light.
See 5.2 “Reading the On Screen Code” on page 80.
Inside LEDs
The LEDs on the electronics module give you
information about the state of the Margay.
See 5.3 “Reading the LEDs” on page 82.
General troubleshooting
Exchange parts from one display to another. This is a
very effective way to find a problem. If the problem
follows the part to the new unit, that part was at
fault.
If the problem stays in the first unit, you haven’t
found the problem yet, but you have learned something: The part you move was not the problem. Put it
back in the original unit and try something else.
Lamp won’t light
Check to make sure the lamp is actually not lit. If
the lamp is lit, you can usually see light if you look
carefully. Light may come through spaces between
parts
Many things can make the screen black, even
though the lamp is lit.
• The Curtain may be on. If the curtain is black and
it is on, the screen will be black.
• There is no source picture. With no valid picture
coming in, the display will be black.
• There is something blocking the light to the
screen. Is the lens cap on?
• There are parts missing in the optical path. If
someone was working on the display, maybe he or
she forgot to put something back in.
If the lamp is not lit:
• No AC coming in? Check the main AC switch on
the display. It should be lit.
• No ballast power? Some displays have a green
LED near the main AC switch that lights when
the 350 volt part of the power supply is working.
It should be lit. Other displays may have an LED
on the electronics module to show when this high
voltage power is available.
78
WARNING
Always turn off the AC power and remove the
power cord before working inside the display
and before removing a lamp.
• If you have AC and ballast or 350V power, try
swapping the lamp into a display where the lamp
is good.
Display A
Display B
Lamp A doesn’t
work here.
Move Lamp A
here.
Move good Lamp B
out temporarily.
a. If Lamp A works in Display B, put it back in
Display A. Lamp A is OK.
b. If Lamp A does not work in Display B, the
problem is Lamp A. Put a new lamp in
Display A.
• If the lamp is OK, try swapping the ballast in the
same way. The lamp ballast provides power to the
lamp. It is an electronic part, and all electronic
parts are eventually subject to failure.
• Fan failed. Most fans are sensed. That means theelectronics module knows whether they are running or not. If they don’t run when they should,
the electronics module turns off the lamp and prevents it from striking (turning on) again.
Swapping other parts
You can swap electronics modules or fans in the
same way to see if one is bad.
When you swap electronics modules, try to put
them back in their original locations. Otherwise you
may have to do setup procedures again, such as Input
Level adjustment and Color Balance, because these
values are stored in the electronics module.
When you swap fans, always exchange fans of the
same size.
Why not use a new part out of the box?
It may seem like a good idea to take a new part out
of the box and substitute it for a suspected part in the
display. However, there is a very tiny chance that the
part in the box doesn’t work.
If you test a part by putting in a known good part,
you get better information.
79
5.2 Reading the On Screen Code
Red and amber lights flashing on the screen can tell you what is wrong.
Turning on the On Screen code
With the remote control, press MONITOR. You
should see the red or amber lights flashing on the
screen. This also opens the Display Status menu, but
of course, you won’t see it if the lamp is off.
If there is a bright picture, it may be difficult to see
these lights. They are soft, out of focus lights. Move
around to see them.
Or, press CURTAIN to make the screen black so they
will be easier to see.
If you see a steady, unblinking, amber light, it
means the lamp is on and there are no alarm conditions. If the screen is black at this time, there are
other reasons for it being black:
• The curtain is on and black.
• The source itself is a black picture.
• There is no source, which turns the screen black.
• There is some foreign object blocking the light
path.

6.1 Changing a Lamp
You can change the lamp from the front or the rear.
When should I change the lamp?
Change the lamp when it fails. Lamp life is the
median life of a large sample of lamps. Median means
middle. It is not what most people think of as average.
Suppose the specification for lamp life is 5000
hours. If you had a large group of these lamps, more
than 100, and you turned them all on at the same
time, after 5000 hours at least half of them would
still be on.
Suppose 50 of these lamps had failed after only 1
hours of use. Then suppose the rest of the lamps
failed after 5001 hours. The average life of these
lamps would be 2501 hours.
But the median life specification is still valid,
because at least half of them lasted 5000 hours. This
is the way all lamp manufacturers specify lamp life—
as the median, not the average.
Taking a different case, suppose the first 50 lamps
failed at 1 hour and the rest of them lasted 10,000
hours. The specification is still valid, because at least
half of the lamps were still working after 5000 hours.
You can’t tell from the lamp life specification how
long any one lamp will live.
Margay lamp life
The median lamp life for the Margay lamp is 6000
hours. If you routinely change the lamp at 6000
hours, you may be throwing away thousands of hours
of useful life. And you may be replacing it with a
lamp that is destined to last less than 1000 hours.
How to change the lamp from the front
1. Open the screen. (See 2.6.2 “Opening or Removing a Screen” on page 34.)
2. Open the door covering the electronics module
(on the right).
3. Turn off the AC power switch and remove the
power cord
86
4. Loosen the screw on the light shield.
5. Lift the cover and latch it.
6. Loosen the lamp screw to the right rear of the
lamp.
3. Loosen the lamp screw.
4. Pull the lamp toward you and to the right.
5. Disconnect the lamp cable.
Replacing the lamp
1. First, plug in the lamp cable. Be sure it is fully
seated.
WARNING
If the lamp cable is not fully seated on the
lamp plug, the lamp will not operate properly.
Overheating may occur.
7. When the screw is loose, move the lamp to the
rear about 3/8" (10 mm), then to the left, and lift
it out, still connected.
8. Disconnect the lamp cable.
Removing the lamp from the rear
1. Turn off the AC power switch and remove the
power cord
2. Remove the rear panel (6 ¼-turn screws).
2. Then mount the lamp in its place. Note the two
pins opposite the lamp screw. These fit into holes
in the optical engine.
3. Close the system following the removal steps in
reverse.
Resetting lamp hours
It is a good idea to reset the lamp hours to zero
when you install a new lamp. (See “Diagnostics:
Hours” on page 107.) This is not absolutely necessary; it is just a way for you to keep track of lamp use.
How to maintain lamp life
There are some actions that can shorten lamp life:
• Turning off AC power when the lamp is on. (Turn
off the lamp with the remote and let it cool until
the fans stop; then turn off AC.)
• Turning a lamp on and off rapidly. (The lamp
should be allowed to heat up fully before turning
it off, at least three minutes.)

6.2 Changing the Air Filter
Clean, cool air is essential for proper Margay operation.
When should I change the air filter?
When it gets dirty, change it.
Unfortunately, there is no absolute rule about
when to change an air filter. For some installations
the environment has clean, dust-free air, such as a
corporate lobby. The air filter may be good for a year
or more.
In other environments—airports, subway terminals—the air full of dust and dirt all the time. The air
filter might have to be changed every month.
Of course, it also depends on how many hours per
day or per week the lamp is on.
How to determine a changing schedule.
Remove and inspect the air filter after three
months of operation. Make a note of the air filter’s
condition. Then check it again after six months of
operation.
These two inspections will give you some idea of
how often the filter needs changing. If it doesn’t need
changing after six months, inspect again in a year. As
long as the environment doesn’t change, you can
build an appropriate schedule in this way.
If new construction occurs in the vicinty of the
Clarity displays, watch out. New construction usually
means DUST.
Removing the air filter from the front
1. From the front, open the screen. (See
2.6.2 “Opening or Removing a Screen” on
page 34.)
2. Open the electronics module door. Turn off the
AC power switch and remove the power cord.
88
3. Loosen the light shield screw. Lift and latch the
light shield in its up position.
4. Lift out the air filter, tilting it forward as you lift.
Removing the air filter from the rear
1. Turn off the AC power switch and remove the
power cord
2. Remove the rear panel (6 ¼-turn screws).
3. Push open the electronics module door.
4. Reach around through this door and loosen the
light shield screw.
5. Push the light shield up until it latches out of the
way.
6. Lift the air filter up and forward, away from you.
89
6.3 Cleaning the Screen and Mirrors
Dirt is everywhere, and unless the displays you service are in a super-clean room, from time to time you
will have to clean the screens, mirrors and lens of
Clarity Visual displays.
• What cleaning product should I use?
• How should I use them?
• How often should I use them?
Cleaning products and how to use them
For mirrors and screens, a foam spray cleaner
seems to work well. It’s is sold under different names
in different parts of the world. It is available from
many janitor supply companies or building maintenance supply companies. Ask for
• Claire #50 glass cleaner, or
• Sprayway #50 glass cleaner
It is probably sold under a local name, but it all
comes from one company. If you ask for either of the
two names above (it is sold under both), you will get
this cleaner under the local name.
This cleaner is good on glass (screens, lenses, mirrors) and acrylic (screens).
Spray it on the mirror, but not on the screen. For
screens, spray it on the cloth, not the screen.
WARNING
DO NOT spray liquid of any kind on the
screen. It can drip down the screen and wick
up between the layers. When liquid gets
between the screen layers, it is impossible to
remove, and the screen is ruined!
Wipe the mirror or screen gently with a lint-free
cloth or lint-free paper (see Cloth below). Turn the
cloth over to the dry side and continue wiping to take
up the haze.
• Glass Wax™ is another good cleaner for mirrors
and glass screens, but it does not work well on
acrylic screens. It is a liquid in a can. You spread it
on, let it dry, then wipe it off.
• Windex™ works well, too. Just don’t spray it on
the screen. (See Warning above.)
Cloth to use
White cotton cloth is better for cleaning than colored cloth. The dyes in some colored cloth tend to
make it less absorbent.
90
Paper towels tend to leave lint. A better paper
towel for cleaning is Scott® Shop Towels. These blue,
lint free, paper towels are generally available at auto
parts stores, home fix-it stores, and hardware stores.
Cheesecloth is another good choice. This openweave cotton material is light and absorbent.
Removing dry dust
Often the cleaning problem is just dust, not fingerprints or other oily dirt. If it’s just dust, wiping with a
dry cheesecloth or a dry Shop Towel will usually do
the job.
Or use one of the cleaning products designed specifically for picking up dust.
• Pledge Grab-It™, from Johnson
• Swiffer™, from Proctor and Gamble
These are synthetic wipes that have a static charge
that holds onto dust. They do a very good job of picking up dust and leaving no lint behind. However, they
will not wipe away grease or oil, such as fingerprints,
and they can’t be used with liquid cleaners.
Cleaning lenses
Clean lenses as you would the glass mirrors. However, because the lens is small, it is easier to spray the
cleaner, if you use one, on the cloth, not the lens
itself.
Where is the dirt?
When you see dirt in the picture, you can sometimes tell where it is by its focus. Use a white test
pattern to see the dirt most easily.
Small specs of dirt or dust that are in very sharp
focus are on the screen itself.
If the dirt is in soft focus, it is probably a smudge
on the large mirror.
Dirt on the output lens cannot be seen in the picture. However, that does not mean you should not
clean this lens. Dirt here will reduce the brightness of
the picture, but it won’t show up as specs in the picture.

7.1 Menu Trees
Picture
The Picture menu has different
items depending on the current
source type. You cannot adjust Frequency in Digital pictures, so that
item is not in the Picture menu
when the selected source is Digital.
You cannot adjust Horizontal Frequency in Analog, because that is
determined by the source, so it is
grayed out.
In the Source line, the left-right keys
choose the source. Other items can
be adjusted if they are not grayed
out.
The Freq/Phase button
opens the Picture menu
directly.
In most menus, this area describes what the selected (highlighted) function will do or what it is used for.

96
Size & Position
Zoom Window is in two parts. Each part lets you control two
sides of the picture using the arrow keys. Zoom is very limited if the Margay does not have the Big Picture key.
Reset All Windows to Default makes all Zoom values zero.
If Big Picture is being used and Wall Mode is on, the Zoom
values go to the Big Picture defaults.
97
Size & Position
Viewport shrinks the picture. In the example menu, the right
side was pulled in 4 pixels. At the bottom of the menu,
Viewport indicates that only 1276 of the DIDs 1280 pixels
are being used. This feature is most useful when each cube
in a wall is fed a separate picture from a video processor. In
such a case, you can’t zoom the picture smaller, but you
can shrink the picture with Viewport.
Reset All Windows to Default makes all Zoom and Viewport
values zero. If Big Picture is being used and Wall Mode is
on, the Zoom values got to the Big Picture defaults.
98
Aspect Ratio & Wall
Press the LEFT ARROW to
open the Scale Mode
choice menu.
Wall Width and Height determine the dimensions
of the Big Picture wall, which is not necessarily
the same as the physical wall (it could be
smaller). The upper limit is 32 cubes in each
dimension. However, this does not mean you can
safely stack Margays 32 cubes high!
Unit Column and Row designate where this
cube is in the defined wall, which is not necessarily the same position as in the physical wall.
The Column can never be larger than the Width,
and the Row can never be larger than the
Height.
When Wall Mode is checked (on), each cube
shows only its segment of the whole picture.
When Wall Mode is unchecked (off), the cube
shows the entire picture.
When the aspect ratio of the source picture and the aspect
ratio of the cube (or the whole wall when in Wall Mode)
do not match, Scale Mode and Justify are used to fit
the picture onto the cube (or wall).
Scale Mode is Fill All, Crop, Letterbox/Pillarbox, Widescreen, Normal Video or One to One.
Fill All stretches the picture as necessary on one axis to fill
the screen. All of the picture is shown.
Crop fills the screen by zooming until the second edges
touch the screen edges and crops the rest. Some of the
picture will be cut off.
Letterbox/Pillarbox fills the screen by zooming until the
first edges touch the screen edges (sides or top-bottom)
and leaves the rest of the screen filled with the Curtain
color. All of the picture is shown.
Widescreen (16x9) forces a 1.77 aspect ratio to display
compressed DVDs correctly. All of the picture is shown.
Normal Video (4x3) may be the best choice for standard
video sources, such as PAL and NTSC.
One to One puts the original picture up pixel for pixel. Its
shape and size will depend entirely on the source. VGA
sources will be small.
Justify moves the picture to the top, middle or bottom, or
to the left, center or right. This has no function when the
Scale Mode is Fill All.
99
Memory
See “Memory: Recall” on
page 101.
See “Memory: Save” on
page 102.
The Delete menu looks like
the Recall menu.
It is not necessary to delete a
memory slot before saving
something new.
100
Memory: Recall
In the Recall grid menu, use the arrow keys to navigate
through the memories that have something stored in
them. The empty memory slots are grayed out and you
can’t land on them. Press ENTER to open the Recall
detail menu.
The detail menu shows what will be recalled when you
press ENTER.
ENTER
When (Current) appears in the Slot to Recall line, it
means that the Margay is already doing exactly what
this slot would tell it to do.
Press SAVE once to
open the Recall grid
directly.
101
Memory: Save
Press SAVE twice
to open this menu
directly.
ENTER
In the Save grid, use the arrow keys to cycle through the
available memories. As you navigate through all 40
memories, Save Now will show (Overwrite), as shown
here, if the slot already has something in it.
For each empty memory, the Name of the memory is the
default name for this slot. You can change this name as
described below. Many lines are grayed out because
you can’t change anything here except the name of the
memory. The lines in this menu are different for saving
different modes: video or digital.
(Overwrite) appears if the Save to Slot number currently
has something saved in it.
To save, highlight Save Now and press ENTER.
A (Current) notice will appear in Save to Slot to indicate
that the save was successful and that the slot now contains exactly what the Margay is doing now.
To change the Name of a memory slot, highlight Name
and press ENTER. A bar appears below the name which
indicates character position. Use the +/– arrows to
move the yellow highlight in this bar. Use the up-down
arrows to change the character at that position. There
are 24 character spaces available.
The default name is an abbreviation of the memory contents: connector used, resolution, wall configuration and
wall position (if wall mode is on).
102
Diagnostics: Display Status

Advanced Options: Color Balance
For a complete description of color balancing, see “Color Balancing a Wall of Margays” on page 52.
Color Temperature sets the color temperature to one of four fixed values (3200K,
5500K, 6500K, 8500K) or to Custom. The
fixed temperatures have preset values for
all the White and Gray settings and are
used primarily in single Margay installations.
Custom is the one for color balancing a wall
of Margays.
Gamma changes the colors slightly for Film
or Video display. Use Film for deeper reds.
Use Video for optimal brightness.
White Boost can increase the brightness of
the brightest parts of the picture. Settings
are Off, Medium, High. Using this control
may alter slightly some of the brighter colors. If used, it should be used on all cubes.
It will be more difficult to color balance a
wall if White Boost is used.
108
Advanced Options: Miscellaneous Options
Beeper makes the Margay make a chirping sound each time a remote
button is pressed (and received by the Margay). The display always
triple-beeps when a button is pressed that tells the Margay to do
something it can’t do, such as turn on the lamps when they are
already on.
Curtain Pattern choose what the screen will show when the Curtain
button is pressed.
Auto Codes causes the Margay to start flashing the On Screen Codes
whenever an event causes the lamps to go out, such as opening the
rear panel.
Plug and Play enables the Extended Display Identification Data (EDID)
that is used by many computers to determine the capabilities of the
monitor. This is a complicated standard, and not all video card drivers and operating systems act the same. If you are having trouble
getting your video card to output a picture when attached to our display, you can try disabling Plug and Play and rebooting the computer, to see if it acts any better. Normally Plug and Play should be
enabled.
Inverted Installation inverts the menus, the picture, and makes the
left-right sense of the image alignment motors switch.
Preferred Aspect Ratio tells the Margay which aspect ratio to use
when the incoming signal may have several choices. For instance,
1024x768 and 1366x768 have similar signal timings, and the Margay
might choose the wrong one. If you application sometimes has
1024x768 but never 1366x768, set this control for 4x3.
109
Advanced Options: Lamp Settings
Auto Lamp On makes the lamp turn soon after AC power is
applied. The Margay must always go through its initialization and
sometimes wait for the lamp to cool.
Lamp Saver causes the lamp to turn off if there is no source for the
specified period of time. When a valid source is re-acquired, the
lamp will turn on again. When the lamp turns off, it must cool
down. If the source is acquired during this cool-down period, the
lamp will turn on after the cooldown period. The Lamp Saver Timeout value ranges from 5 minutes to 24 hours.
110
Advanced Options: Serial Port Settings
Group ID and Unit ID combine to make the two-character
ID for the display. These must be different for each display
is a serial RS232 / RS485 control string. The range of each
is 0-9 and A-Z.
ASCII Response Type and ASCII Response Terminator
are explained in the Margay RS232 Guide, available from
Clarity’s website.
Terminate: In most instances, this is not necessary. Terminating the string unnecessarily can cause its own communication problems. The guide line is: If it works without
terminating, leave it alone. It should only be used on the
last display in the string, if at all.
111
Advanced Options: Auto Setup Options
The checked events occur when
• the input changes, say from XGA to UXGA
• a new source is selected
• you press the SOURCE button.
Retry on lost signal, when checked, means the
Margay will look for a valid picture on the other
connectors whenever sync on the current connector is lost. Margay will stop on the next connector that has a picture (sync).
Do Black/White Levels automatically adjusts the
lightest and darkest pixels to be white and black.
This fully automatic method is prone to errors in
the white level. Semi-automatic level adjustment
is better.
112
Do Frequency and Do Phase automatically adjust the electronics module to
the frequency and phase of the selected
picture.
Do Position puts the upper left pixel of
the picture in the upper left corner of the
LCD.

The cable must be wired straight-thru. You can
tell if a cable is wired straight-thru by looking at its
two ends side-by-side.
1. Hold the cable ends next to each other, both ends
pointing away from you. Have the clips on both
connectors pointing down so you can’t see them.
2. If the color of the wires on the two connectors is
the same, left to right, the cable is straight-thru.
The order of the colors doesn’t matter, as long as
they are both the same.

Having trouble?
Most questions are probably answered somewhere in
this manual. Check the Index.
If the problem you have is completely baffling, call
your Clarity reseller—the company that sold the Clarity display to you.
This is the display’s model name
and model number.
My Clarity Reseller is:
This is the
serial number,
the most important
number.
The serial number is
some letters followed
by numbers, such as
LU0243012
If you can’t contact your reseller for some reason,
Clarity’s contact information is on the back cover of
this manual.
But first!
Get the serial number of the unit you have. The
serial number is found on a label in these places:

Describe the problem
Try to describe the problem in the most precise language you can. Remember, the person you are talking
to or writing to can’t see what you see. Try to use
helpful language.
Un-helpful language:
• It looks funny.
• The picture doesn’t look right.
• The image is bad.
• It isn’t working.
Helpful language:
• I see horizontal streaks coming from the right
side of high contrast edges.
• I see a solid green background has vertical bands
in it.
• Whenever I try to "_______", I get a message on
the screen that says "_________".
• The lamp will not turn on. When I changed it
with another lamp, it still did not turn on.
• There is a black line on the left side, and I can’t
move the picture over there with the Position
control.
• I see flashing red and amber lights on the
screen. (Note the sequence of the colored lights.
It’s important.)
